1 mile = 5,280 feet
\n" ); document.write( "1 hour = 3600 seconds
\n" ); document.write( "if 1 mile/hr = \"%285280ft%29%2F3600s\" = 1.4666ft/s
\n" ); document.write( "then 45 miles/hr= \"23760ft%2F3600s=420ft%2Fxs\" = \"23760x=420%283600%29\" = \"23760x=151200\" = \"x=6.363636\" seconds
\n" ); document.write( "
